You and Jason have had a no-strings-attached thing going on for a while now. Your relationship is purely physical. You both figured it'd be fine since it seemed neither of you had soulmates.

At least until today. You wake up in Jason's bed, and he's already up and panicking.

"Oh, no, this can't be real," Jason mutters, staring at his pinky. He catches you looking and he glances at your pinky. You look down and see what's making him panic so much.

A red string tying your souls together.
